Those I belive are Swift marker lights. I think the Metro had amber ones and not clear. I'm gonna agree with you guys though. It's a Metro since it's 5-door body. The Swift came in 3-door and 4-door sedan in the US.

Metro used those marker lights on all models until 1991 then they used these marker lights from 92-94 on all composite headlight cars (LSi), also the Swift was sold as a 3,4 and 5 door in the US. This is an LSi model based on the composite lights.

It is definitely a reflection (or more appropriately a glare) as the rear quarter window on the right side of the car is a transparent piece of glass. The Van would have the rear quarter window on BOTH sides blocked off. It also appears that there may be someone in the rear seat

These cars are unidentifiable, which is why they are in the comments. But I can tell you, as a person that has owned 20 J-bodies (most of them 92-94 Sunbirds) that none of these cars are even close to a Sunbird.
